i have a new (2005) Ibanez SR900, that has Bartolini electronics--bridge and neck pups each with their own volume control, and a bass- mid- and treble-boost/cut. All of the controls have a center detent. Yesterday I was practicing and noticed that the volume control for the neck pup was turning smoothly from 1 to 11, if you know what I mean. No click in the middle. Is it common for the detent to wear out? Is it worth trying to replace it? Is it a sign of worse things to come for the pot? I don't think I have abused it through overtwiddling. I bought the bass less than a year ago, so I am surprised this happened. Thanks for the feedback.
